The thing is, we actually do have the ability to face supply chain disruptions and most weather events by basically having buffers for goods built up at a societal level from top to bottom.

We just choose not to. From underpaying employees so they can't keep a stockpile at home, to just-in-time delivery all the way at the top. This overly-streamlined way to handle society is what's causing problems. For centuries we've been able to deal with shortfalls and problems for the most part. Obviously famines and the like happened if problems persisted for a long period of time.

But we can design our way out of these problems, we just choose not to.
